Bought an XPS 13 last summer. When I got it, they had left some kind of paper/plastic backing strip inside the CPU fan. The system made a horrific noise when the fan spun up and started grinding against it. Luckily I was able to remove the errant strip and the system has been fairly nice ever since. Unfortunately, I chose 1080p matte screen before their terrible content-aware backlight adjustment setup was discovered. They released a firmware update to fix the 4k glossy screen, but my system with its otherwise fantastic 1080p screen will always have that undesirable quirk. Before that, my Lenovo X230t tablet went through three motherboards before finally stabilizing (bad clock, then bad displayport, then total failure) so yeah, I try to stick with what I have as long as possible, and buy at least one year of warranty to fix the near inevitable defects...
